Abstract
Software based implementation system for pseudodynamic testing realised
within the LabView environment is discussed with an assessment of
algorithmic and control sensitivities in the SDOF set-up. On the algorithmic
level these include the effect of the type of time integration scheme and time
step size, while the control effects are concerned with the method and rate of
loading, controller capabilities and instrumentation accuracy. The
sensitivities are illustrated in two model problems, an inelastic reinforced
concrete column and an elastic steel column.
1 Introduction
Pseudodynamic testing is a combined computational/experimental technique
for evaluating dynamic systems, originally proposed by Takanashi el al. in
1975 [1]. The method relies on modelling inertial and damping forces
computationally
